A Transistor Array, Pre-Biased is a type of transistor array (also called a multielement transistor) that contains three or more interconnected transistors that are already biased prior to being installed on the circuit board. The array is commonly used in video signal switching applications and in portable consumer electronics such as cell phones and PDAs. The pre-biased array is typically made up of multiple low-power transistors, a small capacitor device for storing energy, and some additional components for signal conditioning.

The RN1503 (TE85L,F) is a type of transistor array, pre-biased, which is a popular choice for various applications, including power switching and driving motors. The Reel-to-Reel TE85L/F series of transistor array offers up to eight channels. It is designed as an integrated circuit package that contains two internally preset integrated transistors, three zener diodes and two connections for either one NPN or two complimentary PNP transistors.

The RN1503 (TE85L,F) application field includes the power switching of heavy loads, such as computers and its peripherals, as well as motor drivers in digital instruments like disk drives, clocks, and VCRs. Other applications of the pre-biased transistor array include its ability to withstand heavy current conditions such as flyback circuits and electronic devices that used short circuit protection.

The working principle of the RN1503 (TE85L,F) is based on the transistor array that provides the necessary gain to drive current through the device. The array is usually composed of a combination of two PNP and two NPN transistors. The transistors are configured in a way that allows current to be drawn from the source to the drain for controlling the operation of a load.

The PNP transistors are used to control the current from source to the drain by providing voltage amplification, while the NPN transistors regulate the load current by increasing or decreasing the flow of current. The zener diodes present inside the package help protect the power line from the excessive voltage spikes that might occur due to the switching of the transistors.

The pre-biased transistor array also allows for fast switching, saving time and energy by providing short switching speeds. It can provide high-speed switching between multiple states, allowing the array to be used in multiple circuits, while reducing the cost and complexity of hardware implementation.

In conclusion, the RN1503 (TE85L,F) is a type of pre-biased transistor array that can be used in a variety of applications including power switching, driving and controlling loads or motors, and providing short circuit protection. It provides fast and reliable switching between multiple states, and is designed to withstand heavy current conditions.
